      abstract     = {The experimental endstation at the beamline BL5 of the
                      synchrotron radiationfacility DELTA at the TU Dortmund is
                      optimized for spin- and angle-resolvedphotoemission
                      experiments in the VUV regime. The hemispherical
                      electronanalyzer is equipped with a SPLEED detector for
                      spin-resolved photoemissionas well as a two dimensional
                      delay line detector for angle-resolvedmeasurements. The two
                      detectors can be operated semi-simultaneously,therefore, a
                      combination of spin- and angle-resolved measurements on
                      thesame sample species becomes feasible. In addition, the
                      undulator U250 and theplain grating monochromator beamline
                      BL5 are optimized for high brilliance inthe VUV and low
                      energy soft x-ray range, which is in particular suitable
                      forspin-resolved experiments where obtaining ample
                      countrates is usuallychallenging.At the moment, a
                      time-resolved modus for the experiments is
                      undercommissioning. In a close collaboration with the
                      machine group of DELTA(AG Khan, TU Dortmund), a laser is
                      used to produce ultra-short VUV pulses inthe fs-regime via
                      the so-called coherent harmonic generation principle. A
                      partof this seeding laser can be used as a pump laser for
                      pump-probe experiments.During the last few years, the
                      beamline was mainly used to investigatetopological
                      insulators and thin magnetic films. For those sample
                      systems, thecombination of spin- and angle-resolved
                      photoemission experiments wasessential in order characterize
                      the spin-texture of the electronic band structures.In our
                      contribution, we will show those experimental results and
                      give anoutlook on the new time-resolved modus that is
                      currently undercommissioning.},
